I bought an office key for mac and it was claimed by someone, most likely the merchant, before I could use it. Kinguin customer support took around 10 days to finally resolve the claim and they say since the key was claimed after purchase, it must be my fault. They work with shady merchants so be careful buying from them as Kinguin will do nothing to help you. Kinguin might look cheap but if you run into any problems, they will screw you over.
